A recess portion 14a is formed in the underside of the flange 14 of a tilting holder 13 at a position corresponding to, for example, an "upper right" select switch 4. As a result, the operating pin 10 of the "upper right" select switch 4 has a fixed gap with the flange 14. Consequently, the operating pin 10 of the "upper right" select switch is pressed when an operating lever 15 is tilted. However, the operating range B of, for example, the "upper right" select switch 4 is set narrower than the operating range A of, for example, the "upper" select switch 4 since the pressing of the operating pin 10 of, for example, the "upper right" select switch 4 is delayed by the gap resulting from the recess portion 14a.

A multi-directional switch (1) comprises a joy stick (6) which is inclined for selective operation of a plurality of switch portions. The joy stick (6) includes a support portion (6a) supported pivotally about the bottom end thereof; a slidable contact spherical portion (6b) bulging from the top end of the support portion (6a) and having a spherical surface (6e) slidably abutting throughout the circumference thereof against the inner peripheral surface of a through hole (5a) when pivoted; and an operating portion (6c) projecting through the through hole (5a) adjacent the spherical surface (6e). The outer periphery of a flat surface (6d) of the slidable contact spherical portion (6b) of the joy stick (6) is supported at four circumferentially spaced positions so that the joy stick (6) is returned to a neutral position by the elastic restoring force of the switch portions. A joy stick support structure for the multi-directional switch (1) requires neither a particularly part for returning the joy stick (6) to the neutral position nor a securely determined fulcrum.

It is an object of the present invention to provide an information processor, a schema definition method and program with which it is made possible to generate a schema definition of a relational database and a XML-data schema definition all together. The main part of the present invention is an information processor comprising: an element information storage unit which stores: an element name to identify each of elements which constitute tree-structured data, parent-element identification information for use in identifying a parent element which is a parent of the element, and key information to indicate whether or not the element is a primary key to identify the parent element when the data is managed in a relational database, associating each other; a XML-data schema generation unit which generates a XML-data schema, describing a schema definition for XML to define the data structure, based on the element name and the parent-element identification information; and a RDB schema generation unit which generates a RDB schema, describing a schema definition for a relational database to define the data structure of the data, based on the element name, the parent-element identification information, and the key information.

In the present invention, by selecting an optimum combination of plating layer materials or materials, not only the manufacturing cost of motor brush is reduced but also a plating layer having excellent characteristics is formed in a narrow width on the surface of brush base material so as to have a predetermined thickness. The present invention is formed by a brush sliding portion that slides on a motor commutator and a plate-shaped brush base material that is slender as a whole and supports the brush sliding portion. This brush sliding portion is formed by Pd plating portion formed over a predetermined length on a part in the lengthwise direction of the brush base material that supports the brush sliding portion. This Pd plating is applied on the brush base material via backing Ni plating.
